I've just seen that Etsy shops in the UK can take payment in instalments through Klarna. Will this option be made available to Pattern websites too?
I assume so, but I do not know that for sure. You may want to ask etsy itself. Sorry. Hopefully, someone will come along that has experience with it.
It's available on Etsy but not on Pattern. Etsy has not implemented one thing they've added to Etsy's side to Pattern since Pattern's initial launch, I'm assuming Klarna will not be added as well.
